Magic!: Turning Your Arm Into A Touchscreen

This is a video showing how, by mapping the sound your arm makes when you tap it with a finger, you can turn your whole arm into a touchscreen. A long, hairy touchscreen.

We present Skinput, a technology that appropriates the human body for acoustic transmission, allowing the skin to be used as a finger input surface. In particular, we resolve the location of finger taps on the arm and hand by analyzing mechanical vibrations that propagate through the body. We collect these signals using a novel array of sensors worn as an armband. This approach provides an always-available, naturally-portable, and on-body interactive surface. To illustrate the potential of our approach, we developed several proof-of-concept applications on top of our sensing and classification system.

It's actually pretty neat, especially the phone on the palm your hand part. Now all you need is a speaker and mic implanted and you're good to go-go-gadget call Domino's. Speaking of which -- how is their new recipe? Because one person told me it was good but somebody else said it was like licking a cat's asshole. Which, BTDT, got the shirt, know what I'm sayin'?
